formation. So far, some twelve to fifteen holes have been sunk to 
varying depths and it is of interest to know that practically in every ease 
oil has been found in greater or less amount. As most of these borings 
weie made in greatly disturbed strata it is also fairly reasonable to sup- 
pose that further developments in areas where the rocks are more regu- 
larly disposed will meet with more favourable results. The oil from the 
greater number of the wells is dark in colour and with a marked asphal- 
tic base, having a specific gravity varying from .946 to .971, in this 
respect agreeing closely with much of that already obtained from some 
of the wells in Trinidad. In the wells on the latter island, however, 
there is a greater variety, the oils examined by the government analyst 
of that place ranging in gravity from .826 to .972.
